Pressurized system: Hot coolant can cause seri-
ous burn. To open cap, stop engine, wait until ra-

When a Caterpillar Extended Life Coolant is
used, an extender must be added to the cooling
system. See the Operation and Maintenance
Manual, “Maintenance Interval Schedule” for the
proper service interval. The amount of extender is
determined by the cooling system capacity.
